Liverpool forward Mohamed Salah is "suffering" from being part of an unsettled front three this season, says manager Jurgen Klopp.
He has played in three different front lines in his past three matches.
"Of course he is suffering," said Klopp. "It is specific, offensive play that requires a lot of work and a lot of information."
The front three of Salah, Roberto Firmino and Sadio Mane had become synonymous with Liverpool's aggressive style of play and brought a Champions League and a Premier League title.
"It was a well-drilled machine the front three, everything was clear what we were doing," said Klopp.
